Lectrosonics SR175 - Manual (Page 5)

SYSTEM SETUP AND OPERATION
1) Connect the supplied CH-12 to the power jack on the rear panel.
2) Attach the antenna.
3) Connect the audio cable.
XLR Output:
Pin 1 - ground
Pin 2 - audio (+)
Pin 3 - audio (-)
4) Set front panel switch to "ON."
Check to see that the red POWER LED lights up.
5) Adjust transmitter "GAIN."
This is perhaps the most important step in the set up procedure. (see your transmitter manual
for specific instructions on the proper gain adjustment of your transmitter)
6) Adjust audio OUTPUT level control according to the type of input on your equipment. The input
levels on different equipment vary which may require that you set the OUTPUT control in an
intermediate position of the control. Try different settings and listen to the results. If the output of
the receiver is too high, you may hear distortion or a loss of the natural dynamics of the audio
signal. If the output is too low, you may hear steady noise (hiss) along with the audio.
Note: Do not use the transmitter GAIN control to adjust the loudness of
your sound system.
INDICATORS
CODE - This red LED lights up when the transmitter is turned on. This indicates that the receiver is
getting an adequate RF signal (carrier) from the transmitter and that the code from the transmitter
matches the preset code embedded in the receiver.
POWER - This red LED lights up when the receiver is properly connected to a power supply and
switched on.
LEVEL and LIMIT - The red LED (marked LEVEL) lights up when an audio signal is present at an
adequate level to produce a good signal to noise ratio. The red LED (marked LIMIT) lights up when
the audio level is being compressed in the transmitter. An extremely high audio level may also cause
distortion.
